Application filed November 28,1906. Serial No. 3451230.

To all ywhom it may concern:

. Be it known that l.. JAuEs H. RnINnAnnT, a citizen ol the United States, and a resident ol East, Grange, Essex county? New Jersey, have invented certain new and useful lmprovements in Blade Sharpeners. ol which the following is a specification.

The object of my invention is to provide improved means lor sharpening or honing the edges ol blades for razors, knives or the like, and the invention comprises apair oi rotative straps located side by side and adapted to receive a blade edge between them, said straps being loose at their outer ends so as to swing by centrifugal action against the blade at its edge, and means lor sup porting a blade in proximity to said straps with means lor rotating said straps in reverse directions, whereby as said straps are rotated the centrifugal action imparted to their ree endsavillecause the same to drag along the blade `edge to sharpen or hone the same.

The invention also comprises` the novel details of improvement that will be more fully hereinafter set lorth and then pointed out in the claims.

Reference is to be had to the accompanying drawings vforming part hereof, wherein,

Figure l. is a side ,elevation of a blade Sharpener einbodying my improvements, Fig. 2 is a iace view tht-re el, looking irorn the leit in Fig. l, Fig. 3 is a plan vien, partly in section on the lino, 3, in Fig. l, Fig. l is a. detail view of the strap-supporting shalt, and Fig. 5 is a detail perspective ola holder lor det-.reliably connect,- ing the strap With its shalt.

Similar'numerals oi' reerence indicate corresponding parte in the several views.

At is indicated a suitable frame in which shafts 2 and 3 are journaled in suitable bearings parallel with each other, the shaft 2 being shown provided with a pinion 4 meshing with a gear wheel 5 journaleol upon a suitable shaft 6 carried by lframe l, said gear Wheel being provided with a handle 5 ier rotating it. Gears 7 and 8 setxiired to shafts 2, 3 cause said shafts to rotate simultaneousljyr but in reverse directions. Upon the shafts 2, 3, are mounted straps Q l() Whih extend side by side, and the outer end portions 9, 104, o1' the said straps are free to swing outwardly under centrifugal aetion during their rotation. Said straps are shown coiled around holders ll, Which may be piecesof metal bent to the required shape and to which the straps .may be secured, as by rivets, which holders ll are adapted to be freely slipped over the upper ends of shafts 2 and 3. I have shown said shafts as of Wire bent to iorin two parallel arms at l2. 12', (Fig. 4) over which the holders 11 can be slipped, the space 11B oi said holder being adapted to receive the two arms l2, l? of the strait-for rotatively connecting them together. In Fig. 4f the reversely bent arm l2 oi the shaft is shown connected with the gear '7, (the shaft 3 being similarly bentand l connected with gear Si providing '.i toni einem nn an i i'or relatively connecting nt .Jn

, said gear with holding the two nrnts nl said shaft in relativer the holders ll thus being eew-ntrieolly sumo their shafts. are shown cui. at an :tente-ingle to their-pi:4 ne if iota* ion. and the windingsl oi each strap may be non ett-1, n gelber, as ai ll, to hold the wound paris i i' ilo nr-.p together While permitting tht ir end poi-tien. it ld' io swing outwardl)Y during rota t ii in.

The shalt lil line between said shafts and at one side tht-reel. at riet-n a distance that when the blade lf3 is in the holder il edge will extend parallel to the straps 9 and it) and be in position to be engaged thereby, as shown 17"' The bearing 20 is shown carried upon an arm $20 resting upon part l ol traine l, and shown held thereon by a screw lb entering a threat'led hole in said arm, said screw being shown located in a slot 2Gb in said arm. By this means said arm may be adjusted back and forth and thereby bearing 20, shalt'lQ and the blade holder may be adjusted With respect to the straps, whereby biade 'i6 maybe adjusted toward and from the straps according to the Width of the blade to Cause the straps to act properly against different blades.

To sharpen or hone the blade edge the blade. is mounted in the holder, as set forth, and ivhecl 5 rotated, whereupon the straps 9 and l0 will be rotated in reverse dir ectionel (in the direction of the arrows in Fig. 3,) and Will bear alternately upon opposite sides of the blade edge, and during such rotation the free ends ll, 10: of said straps will swing outwardly to cause them to bear lightly yet'with sulicient force against the blade edge to sharpen it. By the eccentric mounting of tbe straps upon the shafts 2, 3, they will, during rotation, cause blade and its holder to swing iroin to side So that one strap 'will swing the blade over into position to be engaged by the other stia-p,- and vice vc I Changes canbe made in the details and arrangements extends parallel to shafts 2 and and is located in e.

shown and described without departing trom the spirit oi my invention.
